LHaRBG Horsehead combination

LHaRBG Horsehead combination

This is slightly over ten hours of total exposure on the Horsehead nebula (b33) collected over four imaging sessions (one in 2011, two late 2014 and the colour data January 2015). All of these sessions were captured with a QSI583c through a Televue 127is, guided on a Paramount ME. Each set was calibrated with dark bias and flat frames, before being combined in Pixinsight.
